I'm trying to open a program within a panel in VB.Net Application. I can open up other exe's and such (like notepad), but it won't actually open the program I really want it to open within the panel specified. What it is doing is opening up that program outside of the application (like if you opened it from the start menu), not within the application. I really need some way to open this program within a panel on the canvas. Any help is appreciated!
VB.NET:
